How about a helicopter sim? They are virtually non-existant on the Mac.

About everything else you can think of was taken by MAXIS durring the early nineties. Sim farm Sim Ant Sim Safari Sim City Sim City 2000 Sim City 3000 Sim Copter Sim Farm Sim Earth Sim Town Streets of Sim City Sim Tower Sim Dim Flim Shim Skim.....Blah. Did I get 'em all?

Hmmm. How about a Mac Shareware Developer sim? Submarine Sim? Those are pretty popular. How about a sim of a company that sells Sim games? It could be called Sim Maksis.

I dunno. Just a few tired thoughts. I started out serious but lost it when I started naming all the Maxis games.

SimCohol (sounds better than SimBar). Your job is to build a bar. You have to buy better drinks, but you can't necessarily have the "best drink" to do good. You have to diversify. Plus you have to train new bartenders to mix drinks and such. Perhaps even make it Coyote Ugly like and allow people to have bar dancing, and lighting bars on fire. Of course you have to deal with bar brawls and the maffia and prohibition. Just a start.

How about Sim Car, where you would have a car factory right next to the bar, and had to deal with all kinds of manufacturing errors due to excess alcohol and your cars blew up because of that? You might as well start sim police, where you would have to manage a police station and send your cops out to the streets or undercover chasing drug dealers. Maybe you could even include some cool car chases.

SimPeasant
For everyone who wants to see what it was like to be a peasant (i.e. nobody)

SimSpaceStation
Like SimCity, but in space!

SimArmyBase
Build an army base and buy guards etc... and then try and infiltrate it James Bond style
Or attack a friend's...
Or have a huge online game where everyone is a guard except one, and you take turns infiltrating.
Or whatever.

Symnastics
Like THPS but without the skateboards! Can increase abilities to matrix/crouching-tiger-esque moves.

Sim U Dev Games
Develope a virtual game going throug steps that real programmers need to go through (built in graphics, sound, etc)
It would be kind of like a game wizard but a lot simpler. You wouldn't need to see your finished game. It could be set up like SimCinema. At the end, instead of releasing your movie, you would send your game into a virtual U Dev Games contest.

You could also remake Sim Cinema. It would be about 3x easier than U Dev.

Anyways, whatever you choose to do, good luck. Sim Space Colony sounds cool, but the minute you release it you're going to hear from EA's legal department

This would be more than a graphics pack, it would have completely different financial/gameplay models.

For instance, Jake could have a special part of the game do a missile command like thing whenever the station passes through an asteroid belt, or simulate a fire that has to be contained as well as damage control there after. Just don't call it Sim Space.

Cym Space? You'd have to put up with people saying "kime space"... actually, you could tell the lawyers that it was meant to be pronounced "kime", just in case...

Actually, faintly interesting digression... can you get away with that sort of thing? I've heard of Redbook trainers and so on, so presumably it's legally ok... but what if you have something that is actually meant to be pronounced (but not written) the same as some big name?
